Motion Calculators
Kinematics: speed, velocity, acceleration, displacement, SUVAT equations, projectile motion and free fall.
Motion
Velocity Calculator
Velocity from displacement and time (v = d/t), or solve for displacement or time.
v = d / t
Also called velocity formula · v = d/t
Motion
Acceleration Calculator
Acceleration from the change in velocity over time (a = Δv/t), or solve for Δv or time.
a = Δv / t
Also called acceleration formula · a = dv/dt
Motion
Distance Calculator
Distance travelled from speed and time (d = v × t), in any consistent units.
d = v × t
Also called distance formula speed time · how far travelled
Motion
Travel Time Calculator
Journey time from distance and average speed, including stops — with the arrival time.
Time = distance ÷ speed + breaks
Also called time calculator distance speed · how long will it take to drive
Motion
Average Velocity Calculator
Average velocity from displacement and time, or from initial and final velocity.
v̄ = Δd / Δt = (vᵢ + v_f) / 2 for constan…
Also called average velocity formula · displacement over time
Motion
Projectile Motion Calculator
Range, maximum height, flight time and impact speed of a projectile launched at an angle.

Motion
Free Fall Calculator
Fall time, impact speed and energy for an object dropped from a height (ignoring air resistance).
h = ½gt²
Also called falling object calculator · drop height calculator
Motion
Displacement Calculator
Displacement from initial velocity, acceleration and time (d = vᵢt + ½at²), with final velocity.
d = vᵢt + ½at²
Also called displacement formula · distance with acceleration
Motion
SUVAT Calculator (Uniform Motion)
Solve constant-acceleration problems: enter any three of s, u, v, a, t and get the rest.
v = u + at
Also called kinematic equations · equations of motion
Key motion formulas
| Speed | speed = distance ÷ time |
|---|---|
| Velocity | v = d / t |
| Acceleration | a = Δv / t |
| Distance | d = v × t |
| Travel Time | Time = distance ÷ speed + breaks |
| Average Velocity | v̄ = Δd / Δt = (vᵢ + v_f) / 2 for constant acceleration |
| Projectile Motion | Range = v₀cos θ × t · h_max = h₀ + (v₀sin θ)² / 2g |
| Free Fall | h = ½gt² · v = gt = √(2gh) |
| Displacement | d = vᵢt + ½at² |
| SUVAT Calculator (Uniform Motion) | v = u + at · s = ut + ½at² · v² = u² + 2as |
Motion questions
Do the units have to match?
Yes — if distance is in km and time in hours you get km/h. Use the speed converter to switch to mph or m/s.
